Trait composable_allocators::Composable

pub unsafe trait Composable: Allocator {
    unsafe fn has_allocated(&self, ptr: NonNull<u8>, layout: Layout) -> bool;
    fn manages_on_its_own(&self, layout: Layout) -> bool;
}

Safety

The manages_on_its_own function should be pure, i.e. always return same value for same layout.

An implementer of this trait should return true from has_allocated if and only if at least one of the following conditions is satisfied:

• the passed pointer is denoting to currently allocated block,

• manages_on_its_own returns true for Layout used to allocate memory block, denoting by ptr.

Required Methods

unsafe fn has_allocated(&self, ptr: NonNull<u8>, layout: Layout) -> bool

Safety

The ptr parameter should denote a memory block, currently allocated by this or any other Allocator.

The layout parameter should fit the memory block denoting by ptr.
